Description
Summary
macOS Wide-Area Discovery Accepts Arbitrary Tailnet Peer as DNS Authority and Exfiltrates Operator Credentials
Current Maintainer Triage
- Status: narrow
- Normalized severity: medium
- Assessment: Real shipped macOS discovery steering bug, but exploitation needs same-tailnet position, a CA-trusted endpoint, and user selection, so medium not high.

Weakness
CWE-346: Origin Validation Error
The product does not properly verify that the source of data or communication is valid.
CWE-350: Reliance on Reverse DNS Resolution for a Security-Critical Action
The product performs reverse DNS resolution on an IP address to obtain the hostname and make a security decision, but it does not properly ensure that the IP address is truly associated with the hostname.
How to prevent it
- Architecture and Design: Use other means of identity verification that cannot be simply spoofed. Possibilities include a username/password or certificate.
- Implementation: Perform proper forward and reverse DNS lookups to detect DNS spoofing.
